Acute megakaryoblastic leukemia (AMKL) is life-threatening leukemia in which malignant megakaryoblasts proliferate abnormally and injure various tissues. Megakaryoblasts are the most immature precursor cells in a platelet-forming lineage; they mature to promegakaryocytes and, ultimately, megakaryocytes which cells shed membrane-enclosed particles, i.e. platelets, into the circulation.
The megakaryocyte develops through the following lineage: CFU-Meg (hematopoietic stem cell/hemocytoblast) → megakaryoblast → promegakaryocyte → megakaryocyte. The megakaryoblast is derived from colony forming units (CFU-Meg) of hematopoietic stem cells found in red bone marrow.
MKL/megakaryoblastic leukemia 1 (also termed MRTFA/myocardin related transcription factor A) is a protein that in humans is encoded by the MKL1 gene. [5] [6] [7] [8]
Myeloid leukemia is a type of leukemia affecting myeloid tissue. Types include: Acute myeloid leukemia: A cancer of the myeloid line of blood cells, characterized by the rapid growth of abnormal cells that build up in the bone marrow and blood and interfere with normal blood cell production. Chronic myelogenous leukemia: A cancer of the white ...
Acute lymphoblastic leukemia (ALL) 4.0% Acute myeloid leukemia (AML) 8.7% Chronic lymphocytic leukemia (CLL) sorted under lymphomas according to current WHO classification; called small lymphocytic lymphoma (SLL) when leukemic cells are absent. 10.2% Chronic myelogenous leukemia (CML) 3.7% Acute monocytic leukemia (AMoL) 0.7% Other leukemias 3.1%
Specialty: Hematology and oncology: Symptoms: Bleeding, bruising, fatigue, fever, increased risk of infections [2] Usual onset: All ages, [3] most common in 60s and 70s. [4] It is the most common malignant cancer in children, but the cure rates are also higher for them.
Transient myeloproliferative disease develops and may be of concern in fetuses. Features in a review of 39 reported fetal cases include: reduced platelet production often accompanied by significantly reduced levels of circulating platelets; reduced red blood cell production sometimes accompanied by mild anemia; increased levels of circulating megakaryoblasts and white blood cells; grossly ...
In these cases, the mediastinal germ cell tumor develops before or concomitantly with but not after acute megakaryoblastic leukemia. The three most common genetic aberrations in the bone marrow cells of these individuals (representing ~65% of all cases) are inversions in the long arm of chromosome 12 , trisomy 8 , and an extra X chromosome .
